Fits 2013-2018 RAM 2500 and 3500 trucks (6.7L).

The Sinister Diesel Coolant Filtration System is engineered to protect your engine’s cooling components from the abrasive contaminants that lead to premature failure. Diesel engines, including the 6.7L Cummins, often contain residual casting sand from the manufacturing process, as well as metal shavings and mineral scale. These particles circulate through the cooling loop, acting as an abrasive that wears out water pump seals and clogs the narrow passages of the oil cooler and heater core.

This bypass-style system features a CNC machined billet aluminum filter block anodized in signature Sinister Blue. It is designed to filter a portion of the coolant on every pass, effectively cleaning the entire system over time without restricting the primary coolant flow. The kit includes all necessary hardware and brackets for a secure installation using factory mounting points.

• CNC machined 6061 billet aluminum filter head
• Removes casting sand, scale, and metal debris
• Extends the service life of water pumps and oil coolers
• Bypass design ensures no restriction to engine cooling flow
• Kit includes mounting bracket, high-quality hoses, and hardware

Fits select 1999-2003 Ford F-250 and F-350 Super Duty models (7.3L Powerstroke).

Protect your cooling system from premature wear with the Sinister Diesel Coolant Filtration System. Diesel engines frequently suffer from internal contamination, including casting sand and metal shavings, which act as abrasives against your water pump, oil cooler, and EGR cooler.
